plain. It would take a high polish, and, except for the almost total absence of "figure" to give it beauty, it would be valuable for the manufacture of furniture, or any ornamental purposes. The Kranji is chiefly used in Borneo for ship and house-building, but would be useful in a general way, and seems likely to prove fit for many of our requirements.

Remarks.—Nos. 1, 5, and 6 broke with very long fracture; 2, 3, and 4 much shorter, and scarph like.
Only one piece of Kranji was tested for tensile strength, and that proved equal to a strain of 10,920 lbs. on the square inch. None were tried under the vertical or crushing strain.
